The incidence of lumbar spondylolysis has been reported to be generally 3%-6%, and 4%-10% among patients complaining LBP. In athletes, the incidence of lumbar spondylolysis during adolescence has ranged from approximately 15% to 50%. The purpose of this study was to prospectively investigate to determine the imaging and pain characteristics of spondylolysis on lumbar extension among adolescent patients with Low Back Pain (LBP) who played sports.
